I had figured up the cost of building new coops and runs not to mention the labor would be a heavy load. I looked around my garage and noticed that it really wasn't being used for much more than storage ( junk ) It is 30 x 36 I wanted to use 8' of back area and put my runs outside I figured I would still have plenty of garage and 7 new coops. The thing I really like about this setup is that all the watering, feeding and cleaning can be done from indoors and not outside when the weather is bad. I have started constructing the coops they will be 8' x 5'1" I plan to build them as I need them. According to the figures I got from my chicken math I should most likely go ahead and build them all.
